Since the decorators of your views are evaluated during parsing urls.py you have an 'chicken - egg' problem. The method reverse() can't be used since urls.py is not read.
This snippets evaluates reverse() lazy.
Django 1.4 (current trunk) has a lazy reverse.

from django.core import urlresolvers
class lazy_string(object):
def __init__(self, function, *args, **kwargs):
self.function=function
self.args=args
self.kwargs=kwargs
def __str__(self):
if not hasattr(self, 'str'):
self.str=self.function(*self.args, **self.kwargs)
return self.str
def reverse(*args, **kwargs):
return lazy_string(urlresolvers.reverse, *args, **kwargs)
